--Raymond told me about it."

At that he smiled broadly. "Wonderful disguises, eh? Well, I use them
when I think them necessary, and not otherwise. When I started out,
years ago, I used a great many more than I do now. To me a mystery of
this sort is a good deal like a cut-up picture that you give a child to
put together. First, you want to make sure you have all the pieces,
and then you want to sit down, put on your thinking-cap, and match the
pieces together. To you this is an awful tragedy," his tone softened
greatly, "to me it is another case, nothing more. Work such as I have
done is bound to harden a fellow, in spite of all of his finer
feelings. But I feel for you and you have my sympathy."

under the trees which surrounded the mansion.

At length the fellow gained a point almost under one of the library
windows. He gazed around sharply, and then appeared to be searching
for something on the ground. The detective saw him start to pick
something up, but at that moment the side door of the mansion opened
and the policeman came out.

"Hullo! What are you doing here?" demanded the officer.

"Oh, that's all right," was the low answer. "Don't mind me."

"But what are you doing here?"

"Just looking around, that's all."

"You haven't any right in this yard."

"I think I have."

"Who are you?"

"My name is Watkins--Jack Watkins," and then some words followed which
